Woman loses 85 pounds eating at Starbucks everyday

(Scroll down for video) A woman claims to have lost 85 pounds eating only at her favorite restaurant.

Not unlike the famous Subway diet, a librarian claims to have lost nearly 85 pounds eating almost all her food from Starbucks.

The media has already coined it the "Starbucks diet” after Christine Hall, 66, of Virginia revealed that she went from 190 pounds to 115 pounds after two years of buying all of her food at her nearest Starbucks store.

A typical day begins with a cup of oatmeal and black coffee, while lunch and dinner would be either a sandwich or Panini Bistro Box as Chipotle Chicken Wrap, she said in an interview with the news media.

As a law librarian who works two jobs, she said that Starbucks serves as a convenient dining option and ended up being her one and only weight loss tool.

It's a lot of calorie counting, she says, but considering that the nutritional information is clearly on the label, Hall, who is 5 feet 4 inches said watching her calorie intake is very easy.

Meanwhile, her fastidious calorie counting underpins the conclusions of a new study published in the journal Agricultural Economics, which found that women who read labels on food packages are almost 9 pounds lighter than those who do not.

Fast food giant McDonald's also announced that it will begin to publish nutritional information in its more than 14,000 restaurants in the U.S. and drive-thru windows.

For years, Subway sandwich chain used the weight loss success of devoted customer Jared Fogle to promote the brand. Fogle became a spokesman for the company after losing a whopping 245 pounds on a diet on low-fat Subway sandwiches.

Experts warn, however, that a diet that restricts food intake to one type of restaurant or food can be nutritionally unbalanced.
